(Granted under :ne set of March s, 1883. as y mended Apr-u so, 192s; 37o o. G, 157) The invention described herein may be menue factured and used by or for the Goverment for governmental purposes, without the payment to us of any royalty thereon.

This application is a division oi our copendlng application, Serial No. 326,208 illed March 27,

.This invention relates to a machine for acting on cartridge cases, and more particularly to a machine for applyingl a coating of waterproof material to an ordnance device and for wiping the excess material therefrom.

The purpose of the invention is to provide a simple, effective device ior intermittently depositing a uniform waterproof coating-to the ends of cartridge cases.

The specific nature of the. invention as well as other objects and advantages thereof will clearly appear from a description of-a preferred embodiment as shown in the accompanying drawings in which: l

Fig. l is a View in front elevation of the machine for acting on cartridge cases, l

Fig. 2 is a view in left side elevation showing the coating and wiping devices,

Fig. 3 is a plan view partly in section of the varnishing and wiping mechanism,

Fig. 4 is a sectional view on the line Fig. a,

Fig. 5 is a sectional view on the line 5-5 of Fig. 3,

Fig. 6 is a sectional view on the line Sfof Fig. 5, and

Fig. 7 is a sectional view on the line 1-1 of Fig. 4.

Referring to Fig. 1, the machine comprises a work portion referred to generally as A for performing operations on the base of a cartridge case such as venting, inserting a primer, seating and crimping, and detecting for abnormal conditions. The part described generally as B includes the varnishing or waterprooiing mechanism` and a device for wiping the excess fluid material from the cartridge bases.

Cartridge cases are fed from .a hopper I0 through a passage II to a guide channel I2 in a bed plate I2, see Figs. 1 and 2. Channel I2 extends the length of the bed plate and is provided with conventional means (not shown) for indexing a plurality of spaced, inverted cartridge cases to the left. Tools I3 are mounted on a pair of reciprocating crossheads I3 and perform work operations on the basesof the cartridge cases as they are intermittently advanced toward the varnishing and wiping mechanism B.

The bed plate I2 extends at one side of the machine to carry the varnishing mechanism B Vvarnish or a waterproofing material through a valved pipe I3 to a lower tank I1 (Fig. 4) below the plate I3 andthe reservoir I5 adapted to supply varnish through a valved pipe -I8 and trough I9 (Fig.3) to an upper tank 20 above the plate I2. An applicator 2I (Fig. 4) disposed in the lower tank I1 is carried by a bent rod 22 which extends out of the tank and is xed to a vertically slidable bar' 23. The applicator 2l is adapted to enter the mouth of the cartridge case 24 and 'coat the inside wall evenly with varnish.

.'I'he upper tank 20 is disposed at one side of the cartridge 24 which at this stage in-its .travel is raised in the guide channel and is supported by spaced rails 25-25 (Figs. 4 and 5) which engage the rim of the cartridge ase. An applicator 26 associated with the upper tank is carried by a vertically movable slide 21 which in turn is carried-by a horizontally movable slide 28 vmounted in guide 29. A roller 30 on the vertical slide is arranged to engage a transversely disposed arcuate-cam 3| iixed to a bracket 32 and it ls held against the cam by means of a compression spring 33 (Fig. '7) whose lower end is connected to a spring seat 34 carried by the horizontal slide 28.'

The slide 28 is formed with a tubular bearing 35 which slidably receives an end of a rod 36 which is pivotally connected to one arm of a bell crank lever 31. the rod is confined'between the bearing 35 and the outer pivoted end of the rod.r The end of the rod which projects through the bearing carries a collar 39 for engaging the bearing and it also carries a set screw 4 0 for engaging the lower arm 4I of a bell crank lever. The upper arm 42 of this lever is adapted to strike the vertical slide 21 to move the applicator towards the cartridge case 24 where it deposits a drop of varnish on the primer. The slide 28 is moved to the right in Fig. 4 through the intermediation of the spring 38 and it is stopped in a predetermined position by a set screw 43 while the rod continues its movement to strike'the arm 4I. Movement of the slide to the left is accomplished by engagement of the collar 39vwith the bearing 35.

The actuatingirnechanism for the elements carrying the applicators comprises a connecting rod 44 (Figs. 2 and 4) 'which is reciprocated by the main drivey shaft (not shown) and is connected to the lower arm of bell crank'lever 31 pivoted on bracket 32. The connecting rod is A helical spring 3B embracing also connected by means of a link 46 to a lever 41 which is pivotally mounted on the lower part of bracket 32 and has a link 48 connected to the vertically slidable bar 23.

Referring to Fig. 2 there is shown an endless belt 49 trained around spaced lower pulleys 50-50 and a single upper pulley 5| which is slidably mounted on a vertical rod 52 and normally elevated by a spring E8. A ratchet wheel 54 associated with one of the pulleys is intermittently driven by a pawl B5 carried by lever ISB. The lever 56 is actuated by link 5l from the connecting rod 44.

An arm 58 pivotally mounted on the bracket 32 carries a roller 59 which engages the inner reach of the belt above the cartridge case. A link 60 connects the arm with lever 41 and serves to intermittently depress the arm so that the roller will move the belt into contact with the base of the cartridge case in order to wipe excess varnish from the primer.

Referring to Fig. 5, when the cartridge case reaches the end of its travel by the action of the indexing mechanism shown generally as BI, a member 62 on the end of the mechanism pushes the case onto a drying rack @3.

'I'he operation has been described in connection with the description of the component elements. v

We claim: e

1. In a machine, a bed plate, means for moving cartridge cases step by step across the bed plate, an endless belt extending transversely across the pathof travel of the cartridge cases, means for intermittently moving the belt, and means for intermittently depressing the belt into engagement with a cartridge case;l

2. In a machine, a bed plate, means for moving cartridge cases step by step across the bed plate, an endless belt extending transversely across the path of travel oi the cartridge cases, a yielding mounting for said belt, means for intermittently moving the belt, and means for intermittently depressing the belt into engagement with a cartridge case.

3. In a machine, a bed plate, means for moving cartridge cases step by step across the bed plate,

an endless belt extending transversely across the path of travel'of the cartridge cases, spaced pulleys sustaining said belt, a tensioning device for said belt, means for intermittently moving said belt, and a rocker arm engaging the inner reach of said belt for intermittently depressing the belt into engagement with' a cartridge case.
